2 Claims. (Cl. 15588) This invention relates to furniture, and moreparticularly to a childs seat adapted to be placed upon an adults chair,bench, or other horizontal surface, so as to increase the effectiveheight thereof.

One object of this invention is to provide a seat of the above naturewhich includes means for adjusting its height, whereby the seat may beused to support children or other persons of different sizes at thedesired level upon an adults chair for use at the dining table, thetheater, or other places.

Another object is to provide a device of the above nature in which theadjusting means comprises a plurality of interfitting andinterchangeable blocks adapted to be inserted between the top and baseof the seat.

A further object is to provide a device of the above nature which willbe simple in construction, inexpensive to manufacture, easy to installand manipulate, compact, ornamental in appearance, and very eiiicientand durable in use.

With these and other objects in view, there has been illustrated on theaccom anying drawing one form in which the invention may conveniently beembodied in practice.

In the drawings,

Fig. 1 is a plan view of the improved childs seat.

Fig. 2 is a front elevation looking rearwardly from the line 22 of Fig.1the seat member being shown in its lowest adjusted position.

Fig. 3 is a side elevation of the same, looking to the left from theline 33 of Fig. 1.

Fig. 4 is a front elevation similar to Fig. 2, but showing the seatmember adjusted to a higher position.

Fig. 5 is a side elevation of the same, with the top seat memberdisengaged to show the shape of the end slots in the insert block.

Fig. 6 is a perspective View of the end of one of the insert blocks.

Fig. '7 is a perspective view showing the child's seat as it wouldappear when in position upon a chair.

Referring now to the drawings in which like reference numerals denotecorresponding parts throughout the several views, the numeral I0indicates a fiat base member of generally rectangular outline withrounded corners, and having a pair of elongated rectangular supportblocks II, I2 on its upper surface adjacent its opposite side edges. Thesupport blocks II, I2 are secured to the base member ID by a pluralityof headed nails I3 each of which has a scratchpreventing rubber buttonHi secured to the nailhead and located under the base member I0.

Provision is also made of a top seat member I5 having the same size andoutline as the base member In and provided with a pair of dependingrectangular side strips I6, I! which are secured to its undersurface bymeans of screws I8. The upper surface of the seat member I5 preferablyhas a rounded concavity I9 to enhance the comfort of the child using theseat.

The side strips I6, I! are each provided on both ends with pairs ofspring clips 20, 2I whereby said side strips It, I! may be releasablysecured to the support blocks II, I2 of the base member I in order tohold the seat-member I 5 in assembled relation with the base member Ill.

Each of the spring clips 20, 2| ispreferably formed from sheet metal andcomprises a flat base portion 22 which is secured to the lower surfaceof one of the strips l8, IT by means of screws 23. Each clip 20, ZI alsohas a pair of depending side ears Mat opposite sides of the base portion22 and a resilient end tongue portion 25 whi h is bent downwardly andinwardly, as shown.

The end surfaces of the support blocks II, I2 are each provided with aV-shaped slot 26 which forms an inclined surface ada ted to be engagedby one of the resilient tongues 25.'

Thus. it will be seen that the seat member IE will normally be retainedupon the base member Ill, and the resilient characteristics of thetongues 25 will permit the member I5 to be readily disengaged from thebase member ID whenever desired.

A plurality of spare insert blocks 21, 28, 29, 39 are provided for thepurpose of adiusting the height of the seat. The end surfaces of theinsert blocks 21, 28, 29, 30 are provided with V- shaped end slots 3|which have the same shape as the end slots 26 in the support block II,l2. A plurality of spring clips 32, which have the same form as thespring clips 28, 2 I, are secured one at each end of the lower surfacesof each of the spare insert blocks 21, 28, 29, 3!). It will thus be seenthat any desired number of the spare insert blocks may be inserted andengaged between the support blocks II, I2 and the side strips I5, H inorder to bring the. seat member I5 to the required elevation. When usedin this manner, the spring clips 20, 2I, 32 will 00-- operate with theV-shaped end slots 26, 3I in the underlying blocks to hold the partstogether.

3 At the same time, the side ears 24 of the clips 29, 2!, 32 willprevent the blocks from becoming displaced laterally.

It will be noted by reference to Fig. 2 that when the side strips Hi, I!of the top section l are assembled directly with the support blocks I lI2 of the base member It, a storage space 33 will be provided betweensaid top section and base member which is of a suitable size todetachably contain the spare insert blocks 21, '28, '29, 30.

In order to secure these spare insert blocks in the space 33, provisionis made of a pair of insert holding rails 34 which are adapted tofrictionally receive the resilient flanges 25 of the spring clips 32.The insert-holding rails 34 include flathorizontal mounting flanges 35which are secured to the upper surface of the basemember l0 adjacent thesupport blocks I i, I 2 by meansoi screws 36.

It will be understood that the seat may be made of any suitablematerial, such as wood, metal,

plastic, or fiber.

Operation In, operation, the seat may be placed upon a chair C, as shownin Fig. 7, so that a child sitting upon it will be elevated suitably atthe dining table .or other location. If the child is very small it willbe necessary to support him at a higher level, in which case the spareinsert blocks '27, 28, 29, 30 may be used in order to raise the level ofthe seatmember [5, as shown in Fig. 4.

As the child grows older, one or more pairs of the insert blocks may beremoved, so that a seat of the proper height for the child will alwaysbe available.

One advantage of the. improved childs seat is that it will do away withthe necessity for a special high chair.

A further advantage is that the seat may be placed upon .anyconventional household chair,

and inasmuch as it is very compact, it will 00- cupy less space thanwould be required for aspecial chair.

Another advantage is that the seat is entirely self-contained, and whenthe insert blocks are not required, they may be stored within the seatitself.

Another advantage is that the seat will avoid the old expedient of usingbooks, pillows, etc. in order to raise the effective height of a chairso that it may be used by a child.

A further advantage is that the adjustable seat is easily portable, sothat it may be carried to any desired location for use. Thus, the seatis not limited to use at the dining table, but may be taken to theaters,ball games, an other places where it may be used by a child to raise hiseye level to such a point that he can see as well as other spectators.

While there has been disclosed in this specification one form in whichthe invention may be embodied, it is to be understood that this form isshown forthe purpose of illustration only, and that the invention is notto be limited to the specific disclosure, but may be modified andembodied in various other forms without departing from its spirit. Inshort, the invention includes allthe modifications and embodimentscoming within the scope of' the following claims.

Having thus fully described the invention, what is claimed as new, andfor which it is desired to secure Letters Patent, is:

1. In an adjustable seat, a base member, a pair of elongated horizontalsupport block elements fixed in spaced parallel relationship to the topthereof, a top seat member, and leaf spring clip means attached to theunderside of said top seat member and engaged with holding means in theends of said support block elements for detachably holding said basemember and said top seat member interengaged.

2. The invention as defined in claim 1 wherein each of said leaf springclip means comprises a horizontal base portion, a downwardly andinwardly directed tongue portion and vertical ears depending from thesides of the base portion for embracing the sides of said blockelements, the holding means in said block elements being end notchesreceivingsaid tongue portions.
